Espacially this: https://phpdelusions.net/pdo#fetch as it looks like you have mostly anything else. Also have a look at print_r(), var_dump(), htmlspecialchars(), Template Engines and XSS (cross site scripting).

Not just fetch(), there are multiple options open, for example

  • fetch()
  • fetchAll()
  • foreach ($stmt ...)

While reading the item linked to by Barand would be a great place to improve your PDO knowledge, a simple loop on a fetch is the usual way of outputting the results of a query.  One problem with your query though is all you are asking for is a count of the rows that match your where condition.  Don't you want so select some fields from those matching records to be displayed?

After that you simply do this:

echo "<table>";
while ($row = $stmt-fetch(PDO::FETCH_ASSOC))
  echo "<tr>
echo "</table>";

This will give you a nice html table of the results.  You can add your own table headings (th tags) to improve it.  And you could add some css code to make more improvements.

Note - the "fieldname1 and "fieldname2" are made-up names for your query results.  Obviously you would substitute your queried item names for the $row elements.  

PS - you should also add some error handling code to ensure that the query has actually run or that you have some results to be displayed before starting the loop.
